Mark 3:31
Then Jesus's mother and brothers arrived. Standing outside, they sent someone in to call him — the family's arrival, foreshadowed in verse 21, now occurs. They are standing outside — they cannot get through the crowd — and they send a message in to Jesus. The outside/inside spatial distinction sets up Jesus' redefinition of family: the physical family stands outside while the spiritual family (those doing God's will) sits inside around Jesus. The mother and brothers are not presented unsympathetically; their concern is genuine. But the encounter creates the occasion for one of the most radical sayings in the Synoptic tradition about the nature of the kingdom's community.
